My guess is that you have no idea what ventilators are or how they are made. It would take any company a year to convert their production line and another to manufacture enough product. That's why ventilators cost as much as cars to make.

You don't just retool a plant overnight, it's one thing to go from making cars to making tanks and planes like they did in WW II,,, it's a whole different matter to go from making cars to making medical equipment.
